Acer Aspire 9420 Cd Rom driver

hi, I had just installed windows 7 on my laptop. The only issue is that the cd rom is not working and I have this notice on the trouble shooter: "The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)"
This is the device driver details : ONU YV09A7W9E SCSI CdRom Device
System is working on 32bit
Can anyone help me on this?
Thanks Noel

You might try going to device manager and uninstalling the CD Drive and then rebooting and it will re-install on start up. That may help.
